Hi Everyone!

Not sure if this qualifies for "Interesting Questions", but I think it's interesting.
I'm using the FRA to measure the impedance of a system completely comprised of passive components (a transformer and capacitors). When I do this, I'm getting some right half plane zeros. I might be wrong, but I'm pretty sure you can't get a system with RHP zeros without active components. Has anyone seen phase inversion when using the Cleverscope FRA?
